c# - 选择性能计数器类型

Question

问题来了。我正在开发一个名为 CreateCounters 的方法，该方法将为应用程序创建性能计数器。该方法包括以下代码。

void CreateCounters()
{
     if(!PerformanceCounterCategory.Exists("Contoso"))
     {
         var counters = new CounterCreateationDataCollection();
         var ccdCounter1 = new CounterCreationData
         {
             CounterName = "Counter1";
             CounterType = PerformanceCounterType.SampleFraction;
         };
         counters.Add(ccdCounter1);
         var ccdCounter2 = new CounterCreationData
         {
             CounterName = "Counter2";
             // need insert PerformanceCounterType
         };
         counters.Add(ccdCounter2);
         PerformanceCounterCategory.Create("Contoso","Help dtring",
         PerformanceCounterCategoryType.MultiInstance, counters);
    }
}

我需要确保 Counter1 可用于 Windows 性能监视器 (PerfMon)。您应该插入哪个代码段？

有四种选择。

A. CounterType = PerformanccCounterType.RawBase
B. CounterType = PerformanceCounterType.AverageBase
C. CounterType = PerformanceCounterType.SampleBase
D. CounterType = PerformanceCounterType.CounterMultiBase

我不知道是哪一个，为什么？

Answer 1

看这个:

https://msdn.microsoft.com/en-us/library/system.diagnostics.performancecountertype%28v=vs.110%29.aspx

那里有一张表显示 PerformanceCounterType.SampleFraction 需要类型为 PerformanceCounterType.SampleBase 的分母

(并且 RawFraction 需要 RawBase 等)
